For every 1/4" of thickness there is one layer of super-strong fiberglass cloth that stands up to high stress and flex. Use these sheets as flange gaskets, diaphragm packing, and anywhere heavy compression would squeeze nonreinforced neoprene out of place.

One layer of fiberglass cloth is inserted between two layers of silicone rubber to give these sheets and strips the strength to stand up to high stress and flex. Use them as flange gaskets and anywhere heavy compression would squeeze nonreinforced silicone rubber out of place.

A layer of nylon fabric strengthens this EPDM, so it keeps its shape under heavy compression.

One layer of fiberglass fabric is sandwiched between layers of silicone foam giving these strips strength to handle high-stress applications, such as gasketing.
